One Week Manufacture Edition Blue

The Armin Strom One Week Manufacture Edition Blue is a limited-edition timepiece that reimagines the brand’s foundational calibre with a bold, openworked design. Encased in a 41 mm stainless steel case and paired with an integrated steel bracelet, the watch features a striking blue PVD-coated mainplate that replaces the traditional dial, showcasing the movement as the visual centerpiece.

Powered by the manual-winding Calibre ARM21, developed and assembled entirely in-house, it offers a seven-day power reserve via two barrels mounted in series and operates at a frequency of 3.5 Hz for enhanced chronometric stability. A standout feature is its three-dimensional power reserve indicator, driven by a conical gear and polished cone, evoking the mechanics of classic pocket watches. The movement is meticulously hand-finished with Geneva stripes, polished screws, chamfered bevels, and grained surfaces, and each piece is assembled twice to ensure optimal performance and aesthetics. The watch includes a black minute ring, small seconds subdial, and rhodium-plated hands and indexes filled with Super-LumiNova®. With sapphire crystal on both sides and 10 ATM water resistance, this 100-piece edition exemplifies Armin Strom’s commitment to mechanical innovation and haute horlogerie craftsmanship.
